LAM P-SHADE.

SPECIFICATION forming part of Letters Patent No. 394,760, dated December 18, 1888.

Application filed January 12, 1888. Serial No. 260,523. (No model.)

To all whom it may concern.-

Be it known that we, SAMUEL FINN and CHARLES H. SANGSTER, both citizens of the United States, residing at l-luffalo, in the county of Erie and State of New York, have invented certain. new and useful Improvements in Lamp-Shades, of which the following is a specification.

Our invention relates to lamp-shade frames adapted to be covered with silk, paper, or other suitable ornamental material.

The obj ect of the invention is to produce a lamp-shade adapted to be readily adjusted to fit lamps of different sizes, and will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a back elevation. Fig. 2 is a top plan view, and Fig. 3 represents a side elevation.

Our shade-frame is preferably made of wire, as being the best material most suitable for the purpose. Its upper portion consists of the curved radiating frame-pieces 1, having their upper ends secured by being looped or bent over or around the lower central ring, 2, at or about the points 3, and are rigidly secured thereto by solder. The opposite or lower ends, 4, of the curved frame-pieces 1 are secured to the curved ring 5 by being looped over and soldered to it. This ring 5 is made of one piece of wire bent to the desired form and its two ends united by solder, or otherwise secured in any well-known way. Above the ring 2 is preferably secured another ring, (3, by means of the vertical supporting-wires 7, which are looped to the rings 2 and 6, and are rigidly secured by solder. In some cases the upper ring, 6,1nay be dispensed with, and the radiating frame-pieces 1 may be made in any well-known way or in any form desired. To the ring 2 is secured, by being looped and soldered thereto, two vertical supportingbars, 8 and 9, each having at its lower end a horizontally arranged loop portion, 10. Through the loops 10 are passed the vertical bars 11, which pass up and are each secured by either a loop or a short tube, 12, so that the vertical bars will slide up or down with sufficient friction to hold them at any point to which they may be moved. In this way the shade is formed into a spiral, 15.

is made adjustable vertically up or down, and may be thus adj listed to any point desired, the wires or bars 8, 9, and 11 being fitted so as to be held with the necessaryfriction to keep them at any point required. Near the lower portions of the bars 11 they are bent, at or about the points 13, backward and then inward until they meet, where they are secured by a ring, 14, or solder, or by bot-l1, and below this each From the spirals 15 they are bent downward and then forward, so that the curved holding-bars 16 project horizontally, or suli stantially so. These portions 16 are curved so as to leave an opening, 18, (see Fig. 2,) and adapt them to pass over and clasp the neck of a burner, or anything to which it is desired to fasten them.

At the end of one of the holding-bars 16 is secured, by solder or in any well-known way, a chain, 19, and at the end of the opposite holding-bar is rigidly secured a vertical pin,20.

From this construction it will be seen that the size of the opening 18 between these holding-bars can be made larger or smaller by placing different links of the chain over the vertical pin 20, and it may be thus made to fit any size burner or other article to which it may be attached.

The object of the spirals 15, which act as springs,is to provide the means for enlarging the opening 18 by the opening of the springs 15. They are also elastic enough to draw and hold closely to the articles to which they are attached when fastened by the chain 19.

It will be seen that the length or form of the several bent portions may be varied without changing the nature of our invention.

e claim 1. A lamp-shade frame consisting of an upper portion adapted to receive a covering of silk or other suitable material, in combination with a ring, 2, two vertical bars, 8 and 9, and two vertical bars, 11, the two secured to each other so that one pair of bars will slide vertically up or down on the other, the lower portions of the vertical bars 11 being provided with a suitable device for attaching them to a lamp-burner, whereby the shade may be adjusted vertically up or down, substantially as described.

2. A lamp-shade frame consisting of an up per portion secured to the ring 2 to receive 3 01121111 and fastening-pin for adjusting the TO the covering of silk or other suitable mateshade and securing itto lamps of different rial two Vertical supporting-bars connected sizes, slilistmitiailly as described.
